According to the particle model, why does stirring increase the rate at which a solute dissolves in a solvent?
1 )
Stirring adds heat to the solution, increasing the kinetic energy of the particles
2 )
Stirring causes the solute particles to break into smaller pieces that dissolve more easily
Stirring helps solute particles spread out into the spaces between solvent particles more quickly
4 )
Stirring changes the chemical structure of the solute, making it more soluble
